4-Port T1/E1 RJ-48 Interface Network Modules (NM-CEM-4TE1)
The 4-port T1/E1 RJ-48 interface network module (NM-CEM-4TE1) is a single-wide CEoIP network
module with four T1/E1 ports. (See

Connecting 4-Port T1/E1 RJ-48 Interface Network Modules
(NM-CEM-4TE1) to the Network
The 4-port T1/E1 RJ-48 interface network module (NM-CEM-4TE1) uses a RJ-48 straight-through cable
to connect to the customer premises equipment (CPE) for use in T1 or E1 circuit emulation. (See
Figure
All four ports on the network module must operate in the same software-configured mode, either as T1
Note
ports or as E1 ports. The NM-CEM-4TE1 network module does not support combinations of T1 and E1
ports on the same network module.
